Definitely the Universal Parks-- in my experience, teens tend to enjoy the thrill rides and take pictures next to stupid stuff (heh heh, no complaints here)

Especially Islands of Adventure-- that will keep them occupied to tell their Facebook friends. Lots of exciting rides, lots of places to take goofy photos, teens love Harry Potter, and as an adult YOU can still have a good time.

Disney may be too "young" for them in terms of rides (or too "old" with the different shows they may not remember)... and DHS is more show than rides-- not a good combo for ADD teens.

IOA is by far the best theme park for teenagers. Recently stayed at Royal Pacific one week after Harry Potter opened.(Three hours to buy a wand!!!) Family voted it best vacation ever. Only draw back was the 90 minute wait for Forbidden Journey since fast pass didn't cover that ride. Service at the hotel was better than WDW and their fast pass is far superior to Mickey land. Top rides at both parks were as follows: 1.Dragon Challenge, 2.Forbidden Journey,3. The Mummy,4. Rip Rocket( when it was running!!)5. The Hulk. I'm from Massachussetts and love our yearly Florida vacation but must vote Bizzaro(formerly Superman) at Six Flags New England the best coaster on the planet. It's won the Golden Ticket 5 years in a row for best steel coaster.

We always had a blast at Magic Kingdom, we didn't think it was "kiddie" and rather enjoyed goofing off. You also have to remember this was the early and mid 90's also. We also always had a complete blast at DHS but we where in the generation where everything was relevant to us. We grew up with the Muppets, Star Wars and Indiana Jones so we always had a blast. Back then Tower of Terror was a new and amazing thing to us so we had endless fun going threw time and again.

Modern Teenagers are a mystery to me now, their odd little creatures to figure out. If I had to guess they'd probably enjoy Universal better now that there is much more then versus my teenage years. Perhaps even Busch Gardens as it has all the Coasters now.

Yeah, Magic Kingdom has a nostalgic vibe at night for some teens (me included). Maybe we are all crazy, but nothing beats the Haunted Mansion and Pirates at 12am!

I think its dependent on the teen as well. While I have always loved thrill rides, it was never a dealbreaker for me in parks. Some teens it is! You can find something to do for teens at every Disney park.

To be safe, I am still standing by my IOA vote. It has a nice mix of thrills and theming. I also am a little weird because I always thought that Posieden's Fury with the water tunnel to be interesting. Harry Potter should also be pretty popular since this is the age that really grew up on it (perhaps our generation's Star Wars?)

To top it off (and I know I am a bit nuts), give me the late Hoop de Do Show (of course, I can drink now) and the former Adv. Club! Kungaloosh!

I'm 14 and have gone Orlando parks monthly since 04. In my experiences, i think the best option for teens that are coaster enthusiasts(like me!) is Busch Gardens. It's the best place for coasters, with 6(Sheikra, Montu, Kumba, Gwazi, Scorpion and Cheetah Chase, soon Cheetah Hunt), but thats all they offer really, plus the animal exhibits. If you're a HP buff, IOA is the obvious choice. If you want child rides or if you're a Disney buff, MK is for you. If you like technological stuff and cultural attractions, Epcot is for you. If you like live shows and a few thrill rides, DHS is for you. If you're an animal lover and like a small thrill, AK or BG is for you. If you're an aquatics fan, SeaWorld is for you.

But, if you want a place that is enjoyable, thrilling, fun and exciting for teens, adults, little children and everyone else, Universal Orlando(both parks) is your best bet. It has something for EVERY member of the family, whether big(Marvel island, HP, Mummy, Rockit), small(seuss landing, Jimmy Neutron, Shrek, Woody Pecker zone), or whatever. It is enjoyable to me even after going over 100 times! It all depends on what your teen favors the most.
